Anatomico-radiological study of the borderline sella

Multidirectional thin section tomography was performed on 62 excised sphenoidal bones. The pituitary gland was then sectioned and examined microscopically for evidence of microadenoma, cellular hyperplasia or cysts. There is absolutely no meaningful correlation between the radiological and the histological findings. Minor sellar changes in the form of slight irregularity of the lamina dura, asymmetry of the sellar floor or thinning of the dorsum sellae may be found in the absence of any histopathological abnormality.
